Angioimmunoblastic T-Cell Lymphoma: A Case Report

Previously believed to be an exaggerated immune response and not a lymphoma, angioimmunoblastic T-cell lymphoma (AITL) is now recognized as a rare variant of peripheral T-cell lymphoma with an aggressive clinical course and poor response to current therapies. There is no standard of care for treatment, but the identification of extranodal involvement is useful for prognostic purposes since the involvement of more than one extranodal site can escalate the patient’s risk category on the International Prognostic Index (IPI). Here we present the case of a patient with AITL who initially presented with an extranodal disease in the form of a fluorodeoxyglucose (FDG)-avid subcutaneous nodule and probable involvement of the spleen. After two months of treatment, her lymphoma exhibited an escalation of grade and an extensive worsening of Epstein-Barr virus (EBV) positivity.
